SPECIFICATION forming' part of Letters Patent No. 226,093, dated March 30, 1880,

Application iiled January 19, 1880.

To all whom 'it may concern:

Be it known that I, WILLIAM ScoBIE Mc- LEOD, of Kingsville, in the county of Essex and Province of Ontario, in the Dominion of Canada, have invented certain new and useful Improvements in Pumps, of which the following is a specification.

My improved pump is specially designed for use at will as a surface or suction pump, or be submerged in a well, cistern, or reservoir, or used in a portable tank, and as a doubleacting pump for raising water from different wells or cisterns and discharging the same in one or more streams, and to4 this end the invention consists in a pump cylinder divided into two chambers, in the Lipper one of which the piston is adapted to work with induction and eduction side pipes, connected to each end of the upper chamber by horizontal reversible valved sections, the induction side pipes being connected with the lower'chamber bymeans of nonvalved sections, the lower ends of the pump-cylinder and induction side pipes being provided with bottom and side openings and interchangeable plugs and valved sections, whereby the valve-ports may be changed to adapt the pump to the different kinds of work required.

In the accompanying drawings, Figure l represents a vertical section of a pump embracing my improvements, said section being taken through the induction side pipes, and the pump being shown for surface or suction use in a well, the cylinder communicating therewith by a valved connection at its lower end; Fig. 2, a similar section, the lower end of the cylinder being closed and the induction side pipes communicating with separate wells or cisterns, the pump being shown for surface or suction use above the wells or cisterns Fig. 3, a similar section, showing the pump as used with an inclosing portable tank for submerged action, the lower ends of the cylinder and of the induction side pipes being closed and the side plugs of said induction-pipes removed, said pump being also thus used in a cistern or well with the openings e closed and the top openings, e2, open Fig. 4, a similar section taken through the eduction side pipes with the pump used as in Fig. l, and Fig. 5 a horizontal section through the upper valved connections of the induction and eduction side pipes.

The pump-cylinder A is constructed of any suitable material, and is provided 4with a piston, B, and a piston-rod, C, the latter extending through the head of the cylinder and connected with an operating-lever, I), fulcrumed to the pump or some other suitable support.

The pump-cylinder is provided near its lower end with a partition, E, dividing it into an upper and a lower chamber, which are connected with induction side pipes, F, at three points, two aboveand one below the partition E, by means of short removable tubular sections Gr H, the sections G Gr being provided with valves g, and the sections H H are without valves in the lower chamber, d', for the purpose hereinafter more fully set forth.

The induction-pipes F, near their lower ends, are provided with side openings, e, which may be closed with plugs I, and the upper ends oi' said pipes F are also provided with similar plugs K, which lcan be inserted or removed to change the operation of the pump.

The pump-cylinder and inductionpipes, at their lower ends, are provided with removable valved sections M M and removable plugs M3, by means of which the pump may be adapted to the different kinds of work required. The pump -cylinder is provided, also, with vtwo eduction-pipes, N, which are connected with said cylinder at each end of the upper chamber, d, thereof by means of removable sections O, which are provided with valves similar to the sections G. Each of the eduction-pipes is provided with an opening, I), for the discharge of water, and air-chambers Q, the discharge-opening having a discharge-spout, q, to which a hose may be attached for throwing water in any direction.

The removable valve-sections are provided with suitable packing-rings,by means of which water-tight joints are formed, and the pumpcylinder and induction and eduction pipes are held together by means of the clamps S, provided with the clamping-screws T, by means of which they can be tightened upon the parts to be held together.

When the pump is to be used as a surface lifting and force pump the plugs I are inserted in the openings eof the induction-pipes, as are also the plugs K and Min the upper and lower ends of said pipes, as in Fig. 1. The valvesections G of the induction-pipes F are arranged with the valves g g opening into the pump-cylinder, and the valve-sections O of the eduction-pipes N have their valves g opening into the said @duction-pipes, as shown in Figs. 4 and 5.

The lowerend of the pump-cylinderis titted with its valved section M, and this section is attached to the suction pipe extending into the well, cistern, or reservoir. Upon operating the piston, as shown in Fig. l, the valved section M is used, the induction -pipes being closed by the plugs M3 and I, and water will be taken into the cylinder, passing first into the lower chamber, d', of the same, then alternately into each end of the upper chamber, d, through the valved sections G H of the induction-pipes F, and inally out through the valved sections O of the eduction-pipesN and the discharge opening or openings, as shown by the arrows, Figs. l and 4.

When desired to employ the pump submerged, all the lower openings of the pumpcylinder and induction-pipes are closed and the plugs K removed 'and the pump placed in a well, cistern, or reservoir. The piston-rod is then connected with suitable mechanism at the surface for operating it, and the water surrounding the upper part of the pump will be taken in through the top openings, e?, in the induction-pipes, and will follow substantially the same course as above described.

Vhen it is desired to employ the pump for raising from separate wells, cisterns, or reservoirs, the plugs I are inserted in the side openings, e, and the plug M3 in the lower end of the pump-cylinder. The Valve-sections M', being in the lower ends of the induction-pipes, are connected with suitable suction-tubes leading to di'erent wells or cisterus, as in Fig. 2, and upon operating the pump the water will be drawn into the pump from each well or cistern and discharged from the openings in the eduction-pipes in sepa-rate streams. If desired to discharge in a single stream, it is only necessary to stop one of the discharge-openings P.

rlhe valves c of the sections Ml serve to prevent the water from falling back into the cisterns from the pipes F at the moment the motion ofthe piston is changed at each end of its stroke, at which point the piston for an instant is virtually at a stand-still. The said valves also serve to keep the pipes full of water when the pump is idle, so that it will commence operation at once when started, and there will be no delay consequent upon the necessity of drawing water from the wells to ill said pipes at the starting. The same function takes place with the valved section M of the cylinder, although it will be seen that these valves e' are perpetually open when the pump is in operation. They do not open and close with the up-and-down stroke of the piston, but are only employed to keep the pump charged with water at all times.

It will be seen from the above description that a pump having the capacity of four ordinary pumps can be compact-ly formed and secured in a box or casing, which may be mounted on rollers or wheels and used for household, farm, garden, or domestic purposes, or in case of fires. The whole may be made of wood except the caps ofthe air-chambers, piston, and bolts, the wooden parts being soaked in hot oil, which will render the pump more durable and cleanly.

By varying the positions of the interchangeable valved sections other combinations may be made, by which the capacity of the pump may be further increased. For instance, the valved sections G ot" one of the induction-pipes may be arranged to open into the pump-cylinder and the valves of the other out of the same into the opposite induction-pipe, the plug K at the upper end of one pipe being removed, and at the other pipe the plug is replaced by a pipe leading to an air-chamber and dischargeopenings. By reversing the valve-sections the pump can be changed from suction to force.

The pump, as above constructed with the various openings and removable valve-sections and removable plugs, can be easily converted into an ordinary force-pump or double-acting lifting or force pump, and can be adapted for use as a surface pump or submerged pump or a portable garden-pump by making the proper changes or' the parts, which can be readily made, and the whole, by suitable packings, bound together in a compact and water-tight condition of the joints.

In using the pump with a portable tank the bottom of the tank is provided with a anged bottom, with openings for the lower end of the pump-cylinder of the induction-pipes, which openings must be suitably packed, as in Fig. 3. A separate head may be used in the bottom of the tank for this purpose', as shown.

In Fig. 6 I have shown in section the airchamber and a section which connects with the top planking of the well by a flanged base, and for use as a submerged pump, in which the water is taken in through the top openings, e2, all the lower openings being closed by the plugs M3 and I.

I claim- 1. The combination of the pum p-cylinder, divided into two chambers, d d', by a partition, E, near its lower end, its piston and induction and eduction ports, with the induction-pipes, provided with side openings, e, having removable plugs I, and the lower ends of the pumpcylinder and the lower and upper ends of the induction-pi pes F, provided with interchangeable plugs and valved sections, whereby the pump may be adapted as a surface-pump or a submerged pump at will, substantially as specied.

2. The combination, with the pump-cylinder' and the induction-pipes F, connected thereto, as described, of the eduction-pipes N, connected with the upper chamber, d, of the pumpcylinder by means of reversible valve-sections IOO IIO

IZO

G, and the interchangeable plugs and Valved sections of the pump-cylinder and inductionpipes, whereby water may be lifted from two cisterns or reservoirs and discharged in single -or separate streams, substantially as specified.

3. In combination with the pumpcylinder. its induction and eduction pipes F and N, the reversible valve-sections G, whereby the ports of the pump-chamber may be changed at will to adapt the pump to different uses, as specified.

4. The combination of the inclosing-box and flanged supporting-plate with the pump-cylinder, its induction and eduction tubes and valves, and the detachable and interchangeable plugs and valve-sections, whereby the pump may be arranged to take water from the inclosing-vessel, or from a source outside of WILLIAM SGOBIE McLEOD.
